Top 5 Ketone Test Strips Reviewed

Ketone what….??

Ketones are by product of breaking down fats & they can be used by the body as an alternative source of energy to sugar. This process is also known as ketosis.

How to Measure Ketones in Urine?

Pass the test end of the small paper strip directly through your urine stream (alternatively, collect urine in a clean, dry container and dip the strip in afterwards). Shake off any excess, then wait 15 seconds.
Compare the color to the guide on the side of the bottle to find out how “deep” your level of ketosis is.

What is the most optimal ketone level?

Excess ketone bodies are excreted via urine (acetoacetate) and can be measured with urine test by using ketone test strip. This is the fastest, most convenient, and affordable way to measure your ketone level. Low concentrations are a value of under 0.5 mmol/L; moderate concentrations 0.5- 4 mmol/L, values of over 5 mmol/L and above is considered a large concentration of ketones in urine.

Around 1.5 – 5 mmol/L is what’s called optimal ketosis and is recommended for maximum weight loss.

Urine test strips usually come with a colored scale to help you compare your results. The scale usually comes in light to dark purple shades with the darkest shade indicating the highest concentration of ketones.

Deeper purples generally indicate higher levels of ketones. Don’t take this to mean that darker is necessarily better – plenty of people find low-to-mid level ketosis to be a “sweet spot” for linear fat loss and muscle gain while feeling energized.

Remember, the desired range for ketosis is 1.5-5 mmol/L. If you’re number is above that, maybe you’re overdoing it and need to calm down a little bit by introducing higher carb intake, if you’re number is too low then do the opposite; cut your carb for several weeks (50gr/day for 2 weeks) then repeat the test.

If a high level of ketones is produced (usually Beyond 10.0 mmol/L), this can cause the blood to become acidic which can lead to illness and even potential danger to organs if not treated in time. This state is referred to as diabetic ketoacidosis.

Around 1.5 – 5 mmol/L is what’s called optimal ketosis and associated with a variety of health benefits, including weight loss, improved blood glucose control, lower triglycerides, higher HDL levels, and improved mental clarity and energy. Nutritional ketosis may also improve endurance performance and recovery from exercise.
